KEYOU is a young and successful high-tech company from the Clean Mobility sector that develops innovative hydrogen technologies, special components and combustion processes with the help of which conventional engines can be transformed into emission-free hydrogen engines - without major modifications to the basic engine. This ensures economic efficiency, but also scalability. KEYOU-inside technology can be used both ON THE ROAD and OFF THE Road. 
The further development of the classic combustion engine by KEYOU to use hydrogen as a sustainable fuel thus allows a quantum leap in propulsion development. The combination of high efficiency and power density achieves a completely new level. In the end, only harmless water vapor escapes as exhaust gas. The ideal solution for the commercial vehicle sector, with which engine and vehicle manufacturers can offer emission-free vehicles to their customers. The new "green" combustion engine with KEYOU-inside technology means zero emissions, efficiency and cost-efficiency at the same time - without any compromises in performance, payload or range. With KEYOU, "Sustainable Zero Emission" becomes reality.
